Toaill whom it may concern:

Be'itknown that l, WARDGRUNER, a citizen of the United States, residing at Coldwa er, in the county of Branch and State of Michigan, have invented a new and useful Road-Scraper, of which the following is a specification.

blade.

Another object is to provide a. device of this character having a. platform thereon for supporting the driver, it being possible for the driver to control the operation of the machine by changing his position 011 the platform. 7

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinal ter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within. the scone of what is claimed, with- I a u 4 out departing from the spirit or the invention.

In the accompanying drawings the preferred form of the invention has been shown.

inv said drawings :-'--Figure .1 is a plan view of the machine. Fig. 2 is a side eleva lieu thereof. Fig. 3 is an enlarged vertical transverse section through a portion of the blade and showing the means employed for attachingthe platform to the blade.

Referring to the figures by characters of reference 1 designates a scraping blade formed of a heavy elongated sheet-of metal curved so as to form forwardly diverging side Wings 2 and an intermediate or rear crcwnportion Mounted on the trout and back portions of the Wings 2 are front and Specification of Letters Patent. "Application filed August 28, 1912.

I angles as shown at 8, so as to r t ntecnease, 1914. serialmiviaeufifff j reancross strips 4 and 5 respectively, supporting a platform 6 which is mounted on the middle portions of the strips. Extendmg downwardly through the end portions 'of the strips 4 and 5 are coupling bolts 7 the lower ends of which .are bent at right extend through openings 9 formed in the wings 2 along-the center thereof. The bolts .7 are provided with suitable means such as nuts 10, for binding the strips 4: and 5 upon the upper edges of the wings 2.

Draft devices, such as chains l1,'rods or the like may be connected to the cal-id portions onthe front strip 4:, these draft; devices converging forwardly and'being connecte .\to a whitfletree 12.

Int-using the scraper herein described; the Same is drawn forward and the forwardly diverging wings 2 will obviously gather the loosened dir' inwardly toward the center of the sore gel where it will be collected after which", by the scraper, the? collected material can be left in a pile upon the road. Increased pressure can be brought onto the surface oil the road by subjecting the platform (3 to the weight of the driver. The driver may shift his weight towar the front end of the platform and cause the'front ends of the wings or crown portion of the blade will thus be relieved of a considerable portion oi the weight. Obviously, the dirt gathered up by the wings, will be directed inwardly to ward the crown portion" and said crown portion will ride easily over it should the dirt be gathered into depressions in the road. By shifting the weight'of the driver mediate or crown portion 3 of the scraper will dig into the soil with greater force than will the front ends of the Wings 2 and the tendency of the scraper is thus to cut ofl any upwardly projecting portions of the road.

Should the lower edge of the blade 1 become unduly worn, the bolts 11 can be detached from the cross strips 4: and 5, the blade 1 reversed so as to bring its worn edge uppermost, and the bolts 7 swung, within the openings 9 so as to cause them to pro raising the rear portion of 2 to dig into the soil while the intermediate to the back end of the platform, the inter engaging the platform to hold it upon either 10' longitudinal edge of the blade.

In testimony that I claim the foregoing as my own, I have hereto ailixed my signa ture in the presence of two witnesses.
